Tongcao is a kind of Chinese herbal medicine, which can be used to make soup after childbirth to promote lactation. For example, it can be used to stew pig’s trotters with tongcao soup or carp with tongcao soup. First, fry carp on both sides for a few minutes on low heat, then add a large amount of water and the right amount of tongcao and stew for 3 hours. Tongcao can also be used in combination with other herbs, for example, for those whose milk does not flow due to stagnation of qi and blood, some medicines can be added to detoxify the liver and relieve depression. For mothers with insufficient milk secretion, the baby can suck the nipple more often to stimulate the milk secretion and make the milk flow out in time, and also massage the breasts properly to make the mammary glands smooth. In addition, you can use the acupuncture method in Chinese medicine, such as acupuncture points like Hegu, Waiguan, Shaozhe and Tanzhong, which have certain effect on promoting breast milk. In our daily life, we should guide mothers on the correct method of breastfeeding, such as breastfeeding on demand and breastfeeding at night, etc. We should also relax and maintain a calm state of mind, avoid anxiety and tension, and encourage mothers to establish confidence in breastfeeding, which will help the secretion of milk after childbirth.
